Nikkei Falls 1.2% as Oil Spike Revives Inflation Fears

The Nikkei 225 declined 1.18% to ¥38,262 on Friday as surging oil prices amid Middle East tensions reignited inflation concerns, pressuring Japanese equities alongside broader Asian markets.

Yen Weakness Fails to Lift Exporters

Despite the USD/JPY holding near ¥163.69, traditional beneficiaries of yen weakness struggled. Major exporters led the decline, with Toyota Motor falling 1.75% to ¥27,934 and Honda Motor dropping 1.89% to ¥4,422. Sony Group also retreated 1.10% to ¥3,269, suggesting that rising energy costs and global growth concerns outweighed currency tailwinds for Japan’s manufacturing giants.

The weak yen typically provides a competitive advantage for Japanese exporters, but Friday’s session demonstrated how broader macro headwinds can override currency benefits. Industrial machinery maker Fanuc declined 1.46% to ¥3,263, while technology component supplier Kyocera posted the session’s steepest loss, tumbling 3.07% to ¥3,538.

Financial Stocks Buck the Trend

In a notable divergence from the broader market selloff, Japan’s major financial institutions posted gains. Mitsubishi UFJ Financial led the advance, rising 0.94% to ¥3,574, while Mizuho Financial climbed 0.67% to ¥1,670. The outperformance likely reflects expectations that sustained higher oil prices could keep inflation elevated, potentially supporting the Bank of Japan’s gradual normalization path and benefiting bank net interest margins.

This sector rotation into financials suggests investors are positioning for a more persistent inflationary environment, which could accelerate the BOJ’s timeline for policy adjustments despite recent dovish signals from Governor Ueda.

Regional Spillover from Middle East Tensions

Friday’s decline reflected broader Asian market weakness as geopolitical tensions in the Red Sea and Persian Gulf drove oil prices sharply higher. Reports of continued US military strikes on Iranian positions and threats to critical shipping lanes raised concerns about supply disruptions and their potential impact on global inflation trajectories.

For Japan, which imports virtually all of its oil, sustained energy price increases pose a particular challenge. The combination of higher input costs and potential demand destruction from renewed inflation fears created a challenging backdrop for equity valuations, particularly in energy-intensive sectors.

BOJ Policy Outlook Remains in Focus

With the next BOJ meeting scheduled for April 28, 2026, market participants continue to assess the central bank’s policy trajectory amid evolving global conditions. Current expectations favor a hold at the present rate, though Governor Ueda’s commentary on inflation dynamics and global risks will be closely scrutinized. A dovish stance could further pressure the yen, while any hawkish surprises might provide support for the currency but potentially weigh on equity markets.

Friday’s session underscored the delicate balance facing Japanese policymakers as they navigate between supporting economic growth and managing inflation expectations in an increasingly volatile global environment. For NISA investors, the current market dynamics highlight the importance of diversification across sectors, as traditional defensive plays like financials showed resilience while growth-oriented exporters faced headwinds.
